Question

Human eye is sensitive to light of wavelength _________.

• A. $80-280$nm
• B. $280-380$nm
• C. $380-760$nm
• D. $760-880$nm

Answer 1

The correct option is C $380-760$nm

380-760 nm is the wavelength range of visible spectrum. Human eyes are sensitive to this range. The visible light is detected by photoreceptor cells present in the retina. There are two types of photoreceptor cells in the eye, cones and rods. Cones are associated with daylight vision and colour vision and rods are associated with vision under low light.

So, the correct answer is '380-760 nm'.
